openbox

standards-compliant, fast, light-weight and extensible window manager

Openbox works with your applications, and makes your desktop easier to manage. This is because the approach to its development was the opposite of what seems to be the general case for window managers. Openbox was written first to comply with standards and to work properly. Only when that was in place did the team turn to the visual interface.
Funny turn-based artillery game, featuring fighting hedgehogs!

hedgewars

Funny turn-based artillery game, featuring fighting hedgehogs!

Each player controls a team of several hedgehogs. During the course of the game, players take turns with one of their hedgehogs. They then use whatever tools and weapons are available to attack and kill the opponents' hedgehogs, thereby winning the game. Hedgehogs may move around the terrain in a variety of ways, normally by walking and jumping but also by using particular tools such as the "Rope" or "Parachute", to move to otherwise inaccessible areas. Each turn is time-limited to ensure that players do not hold up the game with excessive thinking or moving.
